We herein report a protocol for the asymmetric 1,4-addition of hydantoins to various Michael acceptors by utilizing Cinchona alkaloid-based chiral quaternary ammonium salt catalysts. Various products were obtained with moderate to good enantioselectivities and accompanying computational investigations helped to identify key interactions responsible for the observed selectivity. DFT calculations along
